# Nuked MD: reconstructing the Sega Mega Drive chipset

> Nuked MD reconstructs Sega Mega Drive chipset behavior in C using decapped chip photographs. Its current combination targets an NMOS 68000, NMOS Z80 and FC1004, with separate implementations for video, audio, arbitration, I/O and cartridge handling.
